Neosho National Fish Hatchery Newsletter Current Events in Fish Production Helping the Missouri Department of Conservation Hatcheries Boost Fish Production Numbers Despite poor water quality and low production numbers elsewhere in the state, Neosho National Fish Hatchery’s rainbow trout are fairing well. Neosho staff delivered 10,000 surplus trout to the Missouri Department of Conservation’s Roaring River State Park in Cassville. Missouri Department of Conservation’s Shepherd of the Hills State Fish Hatchery in Branson is currently experiencing warmer-thanaverage water temperatures and reduced water quality. Neosho staff brought 18,000 surplus trout in hopes of helping the state hatchery buffer their losses.

of the Hills State Fish Hatchery picked up 5,800 rainbow trout from Neosho and stocked them into Lake Taneycomo. By the end of November, 12,000 more of Neosho’s rainbow trout will be stocked into Lake Taneycomo.

Endangered Pallid Sturgeon Broodstock Arriving Neosho staff are excited to have endangered pallid sturgeon brood stock on station this winter. Thus far, Neosho has received 6 healthy, wild-caught adult pallids from the Missouri Department of Conservation. All sturgeon received new PIT tags, which means they have not been captured in previous spawning events.

This is yet another project that highlights our appreciation of and continued fantastic working relationship with Missouri Department of Conservation. Neosho hopes to receive more adult pallids from the Missouri River thanks to the field work of US Fish and Wildlife Service’s Fisheries Resource Office in Columbia, Missouri and Missouri Department of Conservation.

Fish Health Inspection at Neosho Last week, Ken Phillips from La Crosse Fish Health Center in LaCrosse, Wisconsin visited the hatchery for our biannual fish health inspection. He inspected all strains of rainbow trout and collected samples for bacterial and viral analysis. Our newest biologist, Melissa Cheung, enjoyed observing and assisting when needed in the routine fish health data collection. Genetics samples of the wildcaught adult pallid sturgeon on station were also taken. These will help us determine if each fish is a true pallid or a hybrid individual. Knowing the genetics of each individual will also prevent inbreeding when the fish are paired for spawning.

U.S. Fish & Wildlife Service Neosho National Fish Hatchery Newsletter Community Activities Spending Time with the Local Community Rain or Shine! Neosho National Fish Hatchery made it out to Barnyard Days, a three day arts and crafts fair located on the edge of town. Despite strong wind and some rain, the annual fair attracted a good turnout from the local community and surrounding towns. Children and adults were attracted to our hatchery display by the live trout tank, free fish tattoos, coloring books, pencils and educational pamphlets. Hatchery staff answered many questions regarding the hatchery’s fish production and historic past in downtown Neosho.

Halloween at the YMCA This year, hatchery staff celebrated Halloween at the local YMCA. Families from the local community were invited to a funfilled educational and recreational event. Hatchery staff were asked to judge the children’s costume contest. Alongside indoor games and activities for all ages, a booth was set up complete with a lifesize model of a paddlefish, educational video about the hatchery, and our very own

hatchery mascot Teddy the Trout. Children and adults of all ages were encouraged to ask questions and take home our educational stickers, postcards, and coloring books.

Networking to Create Better Programs for Children in Nature Assistant Manager Roderick May was invited to the Aquatic Resources Education Association conference in Corpus Christi, Texas from October 17th-21st. The forum was created to allow state, federal, and private organizations to discuss ideas and experience getting children back in touch with nature. Meeting with outreach coordinators from across the U.S., Rod was able to share his knowledge base and experience working with children. The feedback and networking he gained will contribute to our educational hatchery programs with local school districts and visitors. Rod plans to develop a summer program based around an outdoor classroom at our hatchery and is working with the Joplin school district on nature-based curricula. He is also looking forward to sharing nature-based programs at the Neosho library.

Hatchery Improvements A Well Deserved Makeover Hatchery improvements are an ongoing task here at Neosho. Part of this month’s projects involved replacing the siding and gutters of the hatchery’s main building and shop. The older siding, made of wood, was rotting away and needed to be replaced. Our new aluminum siding was completed

October 2008 by a local contractor and his staff. Thanks to their hard work, two of our most visible buildings received a much needed face lift. The new look will last longer, creates less long-term maintenance, and enhances the aesthetics of the hatchery.

In with the New, Out with the Old Neosho is trying a new way to feed the pallid sturgeon. Our old system consisted of a five gallon bucket containing water and a frozen slab of adult brine shrimp. The food was administered to the tank once the slab thawed. This system worked well during the summer months, when air and water temperatures are warmer. However, during the winter months, the method was inefficient. The extended amount of time required for the slab of food to thaw created a challenge for us because we feed the sturgeon three times a day. The new system is a very simple floating cage constructed of a PVC frame (12”x18”) with a

U.S. Fish & Wildlife Service Neosho National Fish Hatchery Newsletter plastic, ¼ inch mesh screen bottom. The new floating cage allows us to use the entire radiant heat of the 6’x24’ tank, rather than a five gallon bucket. This system allows for rapid thawing of the feed and decreases the time involved for multiple feedings a day. The food falls directly into the water, drifting with the microcurrents in the recirculating tanks.
